Stopping and Starting a Horizontally Scaled System

Use this procedure to stop and then start a Lawson system that is set up on multiple machines. You need to stop and then later restart the Lawson system for various reasons, such as because you are upgrading, you have stopped the database, you are doing a backup, or you want to delete an overly large ladb.log file.

To stop and start Lawson on a horizontally scaled system

  1. Stop the WebSphere cluster. Use the instructions provided with WebSphere. When you stop the cluster, all of the WebSphere application servers on the Lawson servers are stopped. The person who shuts down the WebSphere cluster must be a member of the group for Lawson.
  2. Stop Lawson on the primary Lawson server.

    Log into the primary Lawson server, change directory to %GENDIR%\bin, and at the command line, specify this information:

    stoplaw

  3. Stop Lawson on the secondary Lawson servers.

    Log into each secondary Lawson server, change directory to %GENDIR%\bin, and at the command line, specify this information:

    stoplaw

  4. Perform the procedure that required that Lawson be stopped.
  5. Start Lawson on the primary Lawson server.

    Log into the primary Lawson server, change directory to %GENDIR%\bin, and at the command line, specify this information:

    startlaw

  6. Start Lawson on the secondary Lawson servers.

    Log into each secondary Lawson server, change directory to %GENDIR%\bin, and at the command line, specify this information:

    startlaw

  7. Start the WebSphere cluster. Use the instructions provided with WebSphere. When you start the cluster, all of the WebSphere application servers on the Lawson servers are started along with the deployed applications. The person who starts the WebSphere cluster must be a member of the group for Lawson.
